Climate change is a reality and global surface temperature projected to rise substantially in the next 80 years. Agriculture practices will have adapt climate change, also help mitigate this effect using, among other strategies, forest conservation management. Silvopastoral systems been adopted tropical livestock areas but their benefits on thermal comfort reproductive performance of beef cows are not completely known. Therefore, our aims were compare microclimate silvopastoral intensive...
The objective of this study was to verify the effects GnRH on ovulation and pregnancy ewes subjected a short-term synchronization estrus. Santa Inês crossbred Inês/Dorper received 60 mg MAP sponges during 6 days plus 300 IU eCG 30 µg d-cloprostenol 24 h prior sponge withdrawal (SW). Ewes were assigned receive 0.9% NaCl solution (Tcontrol; n = 32) or 25 (licerelin, T GnRH; 34) hours after SW. Each group intrauterine insemination by laparoscopy (n 25) natural mating 41). Artificial performed...
The objective of this study was to compare the effect hormonal treatment duration through use intravaginal sponges impregnated with 60 mg MAP for 6 (G6; n = 10), 9 (G9; 10) or 12 (G12; days. All nulliparous (n 15) and lactating Saanen goats received 37.5 µg d-cloprostenol 200 IU eCG 24 hours before sponge removal during nonbreeding season. After removal, estrus monitored twice a day (06h00 18h00) by fertile bucks. Transrectal ovarian ultrasonography performed after device until ovulation...
This study examined the feasibility of transcervical embryo recovery after hormonal treatment to induce cervical dilation, following 7-day oestrous synchronization protocol in multiparous Santa Inês ewes. A total 23 cyclic ewes received two doses 37.5 μg d-cloprostenol by latero-vulvar route 7 days apart. After second injection d-cloprostenol, were checked for oestrus (every 12 hr) and then mated fertile rams throughout period. All (latero-vulvar) 1 mg oestradiol benzoate either...
Cryoprotectants are required to reduce damage caused the cells due low temperatures during cryopreservation. Antifreeze proteins (AFP) have a well-known role in cell membrane protection, while resveratrol is potent antioxidant. This study assessed effect of association concentrations and AFP I ram semen extender. Pooled four rams was allocated into six treatments factorial arrangement: (CONT, only extender); (ANT: 0.1 µg/mL I), resveratrol, one treatment with two levels (10 µM/mL or 50...
Context Superovulation is still a main limitation of multiple ovulation and embryo transfer programs because its high cost the variability in responses to hormonal protocols used. Aims This study aimed compare effect two doses porcine follicle-stimulating hormone (pFSH) on follicular growth, superovulatory response, vivo production Santa Inês ewes. Methods A total 40 multiparous ewes received Day 0 estrus synchronization protocol were superovulated with either 333 IU (G333, n = 20) or 500...
This study reports the occurrence and appearance of various reproductive tract pathologies small ruminants diagnosed using ultrasound. An eight-year retrospective collected ultrasound data was carried out in Rio de Janeiro State, Brazil from September 2012 to July 2020. A total 3463 animals 16 sheep flocks 10 dairy goat flocks, raised under extensive intensive management systems, respectively, were used study. All submitted an examination their tract. Data analyzed Fisher’s exact test (p <...
